How do I setup multi-factor authenticator app on multiple devices?

Hi there, danjonwig!

Thank you for your sharing how happy you are with the compatibly 2FA app. To address your question about setting up an additional device, it's best to contact Microsoft support for Microsoft Authenticator.

If you have questions on QuickBooks, please don't hesitate to go back to this thread.

Sorry, I should have added: Authenticator can support multiple devices. It’s up to the client .org (in this case intuit) to enable multiple pairings. This is an intuit implementation issue, not a Microsoft  support issue.

Great to hear again from you, @danjonwig.

As your business grows, you can be sure that QuickBooks will grow alongside it. Our Product Engineers are always looking for ways to improve the program’s user interface and features. I’d recommend visiting our Intuit Developers Forum where you directly interact with the developers, product experts and engineers to share your application requests and feedback. 
 
Here’s how: 

1. Go to: https://help.developer.intuit.com/s/.
2. On the Intuit Developer page, go to the right-hand side.
3. Click the Questions tab.

You can also stay tuned to our blog to see what’s in store: https://quickbooks.intuit.com/blog/whats-new.

 
Stay in touch with me if you have other questions about integrating third-party, multi-factor authenticator with QuickBooks Online. I’m here to help.

Wait, the engineers don’t get feedback via the community? So, all the content generated here just goes to waste, unless one of your customers does data entry for you?? That’s nuts!

Shame on INTUIT trying to blame accountant's for Intuit's failure to implement MFA across all of their online platforms and making it mandatory for all logins when a client gets hacked.

Because you and Intuit don't want to do the job you are supposed to be doing for us as accountants, and instead, try to compete with us.  I think it should be an anti-trust violation!

can I use outlook 2FA in desktop premier edition? I just turned it on today and now I can't seem to get email working from QB?

Thanks for joining in on this thread, nicolatopus.

I'd like to share some steps to get email working.

You have the option to use 2FA for your email service. Just make sure that QuickBooks have the proper authentication. 

If you're getting an error that says "QuickBooks is unable to send your email to Outlook", this is usually caused by a settings issue. 

To begin, let's make sure QuickBooks isn't set to automatically run as an administrator.

Here's how: 

1. Close QuickBooks Desktop.
2. Open the Windows Start menu.
3. Type "QuickBooks" into the search. Then right-click the QuickBooks icon and select Open file location.
4. In the folder, right-click the QuickBooks.exe file and select Properties.
5. Click the Compatibility tab.
6. Un-check the Run this program as Administrator option. If the option is grayed out, select Show Settings for All Users. This makes the option available.
7. Hit Apply and then OK.

Once done, open QuickBooks and send a test email or transaction. If you're still getting the error, you can follow Step 2 in this article: How to fix "Error: QuickBooks is unable to send your email to Outlook"

Otherwise, change your email preference. You can find the details in this link: Unable to email transactions or send forms using QuickBooks email service.
